The three bodies had filed the petitions four months after the power tariff was increased by 10 paise per unit on March 23. In the petitions, the power generating bodies had sought for an average hike of Rs 2 in power tariff per unit.

Hearing the petitions today, the OERC rejected the pleas of OHPC and OPGC. However, the petition filed by the Gridco is yet to be heard by the commission.
